REPAIR PROCEDURE:
NOTE: The wiTECH diagnostic application is the only method for flashing ECU’s.
Help using the wiTECH diagnostic application for flashing an ECU is
available by selecting “Help” then “Help Contents” at the top of the wiTECH
diagnostic application window.
NOTE: wiTECH may erroneously give an error message at the conclusion of the
download stating the that the flash was not successful. If there is an error
message after the flash has completed, first confirm that the DTC U1601 is
not present and that the P/N has been updated. If so, start the engine to
confirm the flash was successful. If DTC U1601 is present, OR the P/N did not
update, OR the engine did not start, the flash may have been unsuccessful.
Restart the flash update.
1. Flash reprogram the PCM. Help using the wiTECH Diagnostic Application for flashing
the control modules is made available through the wiTECH Diagnostic Application. For
instructions select the “HELP” tab on upper portion of the wiTECH window, then
“HELP CONTENTS”. This will open the Welcome to wiTECH Help screen where help
topics can be selected. After PCM reprogramming has completed successfully,
the following must be performed:
2. Power down the PCM (key off) after flash. Automatic Transmission equipped trucks
must have key off for 10 minutes. Manual Transmission trucks must have key off for
75 seconds.
3. Perform a Quicklearn procedure on Automatic Transmission equipped trucks. Follow
the detailed service procedures available in DealerCONNECT/TechCONNECT, Refer
To Group 08 - Electrical > 8E - Electronic Control Modules > MODULE, Transmission
Control > Standard Procedure > Quicklearn.
4. Clear any DTC's that may have been set in other modules due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allow the
tech to clear them.
5. Type the necessary information on the “Authorized Modification Label” and attach it
near the VECI label.
